An integral decompression bra without shoulder straps

Abstract

The invention provides a bra capable of integrally reducing pressure without slipping-off of shoulder straps. The bra comprises a bra body; the bra body comprises cups, steel rings, pulling racks and shoulder straps, wherein the tail ends of the pulling racks are provided with back hook parts; the upper and lower edges of the pulling racks are separately provided with elastic fabric patches; the bra body is provided with an air interlayer which is located at the side, close to a bra wearer, of the steel rings; the air interlayer is provided with an upper fiber surface, a lower fiber surface and a supporting fiber surface, and the supporting fiber surface braids the upper fiber surface and the lower fiber surface together; and each of the shoulder straps has a length of L, a width of W and a maximal stretching length of Lb, pulling force generated after stretching to a length of delta L is F, a ratio of Lb to L is no less than 2 and no more than 2.5, and a ratio of F to (delta L)*W is no less than 0.68 N / cm<2> and no more than 0.95 N / cm<2>. The bra provided by the invention can alleviate pressure of the shoulder straps on the shoulders and prevent the shoulder straps from slipping off; the elastic fabric patches can mitigate pressure on the body and reduce sensitivity; and since the air interlayer is additionally installed, pressure of the steel rings on the wearer is alleviated.

Description

technical field [0001] The invention relates to the technical field of underwear, in particular to a bra with shoulder straps that cannot be decompressed as a whole. Background technique [0002] Bra is one of the underwear used by women, which provides external support for the breasts, increases comfort and mobility. [0003] Currently marketed bras are provided with two rubber tendons with a certain thickness at the frame position, and the pulling force is greater than that of the frame; the upper one connects the armpit end of the steel ring to the back hook, and the lower one connects the bottom of the cup to the back hook. When under force, most of the force is transmitted by these two rubber bands. Because the rubber bands are generally 10-12mm wide, the force-bearing area is small, and there will be indentations on the body. Long-term wear can easily cause skin allergies and poor comfort. , making the embarrassing situation that women often pull the bra rack in publi...
